Note. End of Year measures included: WJ-III Passage Comprehension (W5PC), WJ-III Letter-Word Identification (W5LWI), WJ-III Word Attack (W5WA), TOWRE Composite (W4TOWRECOMP), and Continuous Monitoring of Early Reading Skills (W5CMER). For each end of year measure the method used was the final status score. The cut-points included .5, 1.0, and 1.5 standard deviations below the mean the normative sample for TOWRE, WJ-III Letter-Word Identification, Word Attack, and Passage Comprehension and a benchmark of 40 WCPM on the CMERS . Growth measures included the Test of Word Reading Efficiency (TOWRE) composite and Continuous Monitoring of Early Reading Skills (CMERS). Growth methods included Intercept (INT), Slope (SLOPE), and Dual Discrepancy (BOTH). Growth cut-points included .5, 1.0, and 1.5 standard deviations below the mean of typically developing control group. IR M1 represents the proportion of students identified as inadequate responders (IR) for Measure 1 (M1). IR M2 represents the proportion of students identified as inadequate responders (IR) for Measure 2 (M2). Agreement IR represents the proportion of students identified as inadequate responder on Measure 1 and Measure 2. Agreement AR represents the proportion of students identified as adequate responder on Measure 1 and Measure 2.
